Influence of Temperature on Analytical Description of Cyclic Properties of Martensitic Cast Steel

並列摘要


The paper presents the results of experimental verification of analytic model of cyclic properties description. The subject of verification was the two-parameter model of Ramberg-Osgood (R-O). The research was carried out at two temperatures using the test pieces of high-chromium martensitic cast steel. The model was assessed by making a comparison of parameters of the hysteresis loop obtained from the calculations using the R-O model. Analysis of the tests and calculations results revealed their diversity depending on the temperature and level of strain covered in the research.
